To all whom it may concern:

Be it known that I, HARRY L. BALDWIN, citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Electric- Lighting Ga Burners, of which the following is a speciiication.

The present invention provides novel gas lighting means for hand operated gas burners of the type equipped with spark producing means actuated by the act of turning on the gas.

The objects sought are to prevent waste of electric energy; to minimize wear on the electrodes and gas valve; to reduce the cost of maintenance to the smallest amount possible; to devise effective, durable and simple gas lighting means readily adaptable to any hand operated gas burner and positive, certain and reliable in operation, and to supply a burner of the type aforesaid which will not be liable to hang and which is easily operable both when turning on or shutting off the gas, the spark being produced when the gas is turned on and the electrodes clearing each other when the gas is turned ofi.

For a full understanding of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings.

While the invention may be adapted to diiferent forms and conditions by changes in the structure and minor details without departing from the spirit or essential features thereof, still the preferred embodiment is shown in the accompanying drawings, in which:

Figure 1 is a perspective view of a hand operated gas lighting burner embodying the invention. Fig. 2 is a side view thereof, the full lines showing the normal position of the parts when the gas is shut off and the dotted lines showing the position of the parts when the gas is turned on and the spark about to be produced. Fig. 3 is a front view. Fig. 1 is a perspective View of a modification. Fig. 5 is a View similar to Fig. 3 of a further modification.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters] The burner 1 may be of any make or design and. is provided with the usual tip and the accustomed valve or gas cock 2 for regulating the flow of gas. A lever 3 is provided for operating the valve or gas cook 2 and may have direct connection with the latter, as indicated in Figs. 1 and 5, or may be mounted upon a stud 4:, as shown in Figs. 2 and 3, said stud projecting from the body of the burner and the lever 3 having connection with the valve or gas cook 2 so as to oscillate the same. As indicated in Figs. 2 and 3 a pin 5 projects outward from the gas valve 2 and is arranged eccentric thereto and enters a slot 6 provided in the lower portion of the lever 3. Any suitable means may be provided to limit the movements of the lever 3, such as a stop 7 which may consist of a pin projected outward from the burner and adapted to operate in a cut away portion of the lever 3. A cross head 8 is provided at the upper end of the lever 3 and terminates at its ends in wings 9 which support an arm 10. An electrode 11 is mounted upon the arm 10 and moves therewith into and out of the way of an electrode 12 attached to the burner 1 near its tip and electrically insulated therefrom. The arm 10 may be mounted either to rock, as shown in Figs. 1, 2, 3 and 4.-, or to oscillate, as indicated in Fig. 5.

In the preferred construction, the arm 10 is mounted to receive a rocking movement, the projecting end being out of axial alinement, whereby upon the application of force to move the lever 3, the arm is rocked either to throw the electrode 11 into or out of the way of the electrode 12 according as the gas is to be turned on or off. An end portion of the arm 10 projects beyond the cross head and is formed with an off-set 13 which throws the outer end of said arm out of line with the inner end. The oif-set portion 13 operates between a pair of pins 14 which are so positioned as to limit the rocking movements of the arm. An operating wire 15 is loosely connected with the outer end of the arm 10 and serves to rock the latter both when said wire is pulled upon to turn on the gas, or pushed upon to turn the gas ofi. When pulling upon the wire 15 the arm 10 is moved to throw the electrode 11 into the way of the electrode 12, and upon pushing upon the Wire 15' the arm 10 is moved to throw the electrode 11 out of the way of the electrode 12. A spring maybe arranged to cooperate with the arm 10 to insure positive movement thereof and to over- I the gas has been turned on and lighted, so come the weight of; the operating wire 15. as to throw the. electrode 11 out of the way As indicated in Fig. 2, the spring 16 is of the coil type and mounted upon the arm 10, one end of said spring operating against the cross head 8 and its opposite end upon the arm 10. As indicated in Fig. 4, a fiatspring 17 is connected at one end to the lever 3 and its opposite end cooperates with a tongue 18 projected from the'arm 10. A spring 19 of the coil type has one end connected with the burner and its opposite end attached to a pin 20 projected from the arm 10. The spring 19 is of the contractile type and is arranged to hold the lever 3 in either of its two extreme positions and also to carry said lever to the end of its movement in either direction after clearing the dead point.

In the construction shown in Fig. 5, the arm 10 is mounted at one end in a wing 9 of the cross head 8 and its opposite end portion passes through an inclined slot 21 formed in the opposite wing. In this con struction, the arm 10 receives an oscillatory movement in contradistinction t0 the rocking movement of the arm as mounted in the remaining figures. When pulling upon the operating Wire 15, the projecting end of the arm 10 is moved downward and inward bythe action of the inclined slot 21, thereby bringing the electrode 11 into the way of the electrode 12, as shown most clearly by the dotted lines in Fig. 5. Upon pushing upward upon the wire 15, the outer end of the arm 10 is carried upward in the inclined slot 21, thereby movingthe electrode 11 outward so as to clear the electrode 12 upon the movement of the lever 3 to turn off the gas. j

i prising a gas valve and a fixed electrode, a

The remaining parts are arranged substan-- tially in the manner set forth in connection with Figs. 1, 2 and 3.

When the gas is turned off, the lever 3; and cooperating parts occupy the relative positions shown in Figs. 1 and 2, (the full lines in the latter figure), and when the gas is turned on the parts occupy the position substantially as indicated by the dotted lines in Fig. 2. The initial pull upon the wire 15 either rocks or oscillates the arm 10 to move the same to bring the electrode 11 into the way of the electrode 12. A continued pull upon the wire 15 moves the arm 3 to both turn on the gas and to bring the electrodes 11 and 12 into and out of contact so as to produce the spark for lighting the gas at the burner tip. To turn off the gas an upward push upon the wire 15 insures movement of the arm 10 to carry the electrode 11 out of the Way of the electrode 12 and to rock the lever 3 to operate the gas valve or cock 2 so as to turn on the gas. It is to be understood that the spring provided to cooperate with the arm 10 may move the latter at the end of the movement of the lever 3 after of the electrode 12. Vhen the spring so acts, the upward movement of the wire 15 serves simply to move the lever 3 to turn off the gas, as will be readily understood.

In the construction shown in Fig. l the spring 17 performs substantially the same ofiice as the part 10, 2'. 6., it acts as an arm to carry the movable electrode 11. WVhen the arm 10 is rocked in one direction the tongue 18 is withdrawn from the part 17 which by its resiliency springs inward to bring the electrode into position to engage with the electrode 12. arm 10 in the opposite direction brings the tongue 18 in contact with the spring arm 517 and moves its end outward to carry the A movement of the electrode 11 out of the way of the electrode 12 upon the return of the lever 3 to normal position.

Having thus described the invention, what is claimed as new is 1. In an electric lighting gas burner com prising a gas valve and a fixed electrode, a lever arranged for actuating said gas valve to turn on or off the gas, said lever having a cross head provided with wings, an arm, mounted in said wings and adapted to recei-ve a movement and having an end portion" extended beyond the cross head, a movable electrode carried by said arm, and operating means applied directly to the ;outer end of said arm to move the latter upon the initial application of force to. throwthe movable electrode into or out ofthe way of the fixed electrode and to move said lever to turn-the gas on or ofi.
